a box of cereal contains 15 ounces of cereal there are 9 servings of cereal in the box each serving of cereal has 140 calories which expression could you use to find the number of calories in 1 ounce of cereal
A 140 - 15 * 9
B 15 * 140 / 9
C (9 * 140) / 15
D 15 * 9 / 140
Answer:
(9 * 140) / 15
Step-by-step explanation:
For each serving it is 140 calories, and there is 9 servings in that cereal. So you want to multiply 9 by 140. And there are 15 ounces in the box so the amount of total calories are to be divided by 15. Thus C should be the right answer.

Draw 2 cards from a standard deck of 52 cards. What is the probability that the first card is a queen and the second card is a king?
Answer:
4/663
Step-by-step explanation:
There are four queens. The probability that the first card is a queen is 4/52.
There are four kings. There are 51 cards left after the first card has been drawn, so the probability that the second card is a king is 4/51.
Therefore, the probability that the first card is a queen AND the second card is a king is:
P = 4/52 × 4/51
P = 4/663
The probability of drawing a queen first and a king second from a standard deck without replacement is 1/663.
The student is asking about the probability of drawing two specific cards from a standard deck of 52 cards. To calculate this probability, we need to consider the sequence of events without replacement. For the first card to be a queen, the probability P(A) is 4/52 because there are 4 queens in a deck of 52 cards. After drawing a queen, there are now 51 cards left in the deck. The chance that the second card is a king, P(B), is then 4/51, as there are still 4 kings but only 51 cards remaining.
The two events are dependent since the outcome of the first draw influences the second. Therefore, the combined probability of both events occurring is found by multiplying the probabilities of each event:
P(A and B) = P(A) × P(B) = (4/52) × (4/51)
This gives us P(A and B) = 1/13 × 1/51, which simplifies to 1/663.
Which is the graph of the function f(x)=x^2+2x+3
Answer:
not one of those two...
Step-by-step explanation:
are there other options? when graphed on desmos it looks like this...
The graph of the given function f(x) = x² + 2x + 3 is attached with the answer. It is not from the given two options.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The given equation is quadratic f(x) = x² + 2x + 3 so the curve on the graph will be parabolic.
When we put the different values of x in the input function f(x) the output function varies in the form of the parabolic curve the equation is quadratic so it will give two solutions which cut the axis at the points ( 0,3) you can see in the attached graph.

A bag contains 10 counters. 6 of them are white. a counter is taken at random and not replaced. A second counter is taken out of the bag at random. Calculate the probability that only one of the two counters are white
Answer:
[tex]\frac{8}{15}[/tex]
Step-by-step explanation:
The ways we can get "1 counter to be white out of 2 draws" is:
1. If 1st one taken out is white and next one different color, and
2. If 2nd one taken out is white and 1st one different color
In probability, AND means MULTIPLY and OR means ADD
Here, we are actually looking for ways of 1st one white, next one different OR first one different and next one white. Let's find them separately.
1. If 1st one taken out is white and next one different color
there are 6 white and 10 total, so 1st one white is 6/10
not replaced, so now there are 9 total and 4 of them are different,so different probabililty is 4/9
We multiply these two to get: 6/10 * 4/9 = 4/15
2. If 2nd one taken out is white and 1st one different color
probabilty 1st one different color is 4/10 since 4 are different and we have total of 10
since not replaced, now we have 9 total and still 6 white.
probability of white in 2nd draw is 6/9
We multiply these two to get: 4/10 * 6/9 = 4/15
Now we add these 2 as stated earlier, so 4/15 + 4/ 15 = 8/15

James's weekly quiz scores are shown in the stem-and-leaf plot below.
If he drops his scores from the first two weeks, his mode score increases by $2$. How much would his mean score increase?
Answer:
By 0.75
Step-by-step explanation:
From the stem-and-leaf plot you can find James's scores:
79, 81, 83, 83, 83, 85, 85, 88, 94, 99.
The mode is 83 (most often score). If he drops his scores from the first two weeks, his mode score increases by 2. This means that the mode became 85 and the data looks like
79, 81, 83, 85, 85, 88, 94, 99.
Now find two means.
1. The old mean:
[tex]\dfrac{79+81+83+83+83+85+85+88+94+99}{10}=\dfrac{860}{10}=86;[/tex]
2. The new mean:
[tex]\dfrac{79+81+83+85+85+88+94+99}{8}=\dfrac{694}{8}=86.75;[/tex]
Thus, the mean will increase by 0.75.

8 Look at the following nutrition label.
Nutrition Facts
Serving Size 1/2 cup (1159)
Servings Per Container About 4
Amount per serving
Calories 250
Calories from Fat 130
% Daily Value
22%
45%
Total Fat 14g
Saturated Fat 9g
how many calories are in 1 cup?
Final answer:
To find the number of calories in one cup, we double the amount of calories in a 1/2 cup serving. In this case, 250 calories are in 1/2 cup, so 500 calories are in one full cup.
Explanation:
To calculate the number of calories in one cup based on the given nutrition label, we can use a simple multiplication. Given that 1/2 cup contains 250 calories, we just need to double this amount, because 1 cup is equivalent to two servings of 1/2 cup each.
The equation to find the calories in one cup is:
Calories per 1/2 cup × 2 = Calories per cup
Therefore, the calculation would be:
250 calories × 2 = 500 calories
So, one cup of the food item contains 500 calories.

The value of the conditional probability is given by Bayes theorem and the value of P ( A | B ) = 0.1333
What is Bayes Theorem?The likelihood that an event will occur based on the likelihood that a comparable outcome will occur in the future. The theorem offers a method for updating existing predictions or hypotheses in light of fresh or updated data. This is known as conditional probability.
Bayes Theorem states that based on past knowledge of circumstances that could be relevant to the occurrence, the Bayes Theorem estimates the likelihood of an event.
And , P ( A | B ) = [ P ( B | A ) P ( B ) ] / P ( A )
Given data ,
Let the conditional probability be represented as P
Now , the value of P ( A ) = 0.9
The value of P ( B ) = 0.6
The value of P ( B | A ) = 0.2
From the Bayes theorem , we get
P ( A | B ) = [ P ( B | A ) P ( B ) ] / P ( A )
On simplifying , we get
P ( A | B ) = [ 0.2 x 0.6 ] / 0.9
P ( A | B ) = 0.12 / 0.9
P ( A | B ) = 0.1333
Hence , the Bayes theorem is solved

Let's solve for x.
2x−9y=14
Step 1: Add 9y to both sides.
2x−9y+9y=14+9y
2x=9y+14
Step 2: Divide both sides by 2.
2x /2
= 9y+14 /2
x= 9 /2 y+7
We need to solve for x.
2x - 9y = 14
Move the 9y to the right side and use inverse operations.
2x = 14 + 9y
Divide both sides of the equation by 2.

Heather received a 32% discount on a $34 shirt. After the 7% sales tax was added, how much did she pay for the shirt.
Answer:
24,74
Step-by-step explanation:
the price with tax= 34 : 100 x 107= 36.38
( start price : 100% x 100% with the 7% tax)
now you can calculate the discount = 36.38 ; 100 x 68= 24.74
( start price : 100% x 68 because the full price is 100% but there goes 32 from off so 100-32 = 68)
A percentage is a way to describe a part of a whole. The final cost of the shirt is $24.74.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
The original cost of the shirt is $34, now since a 32% discount is given the cost will be,
$34 - (32% of $34)
= $34 - $10.88
= $23.12
Further, 7% tax is paid on the cost of the shirt after the discount, therefore, the final cost will be,
Final cost = $23.12 + (7% of $23.12) = $24.74
Hence, the final cost of the shirt is $24.74.
